Staff on Leona Lewis' 'Labyrinth' tour are reportedly furious with her policy of not allowing meat to be brought anywhere near her.
Leona Lewis's tour crew are threatening to quit over her catering policy.
The 25-year-old singer - who has been a strict vegetarian since the age of 12 - has banned all animal products from her 'Labyrinth' shows, much to the fury of her staff, who can't even bring in meat from outside.
A source told The Sun newspaper: "There are going to be murders. Leona has demanded that only veggie food be made available for everyone - and members of the crew are threatening to quit. She will not even allow food to be bought off-site then brought in."
The singer was also blasted for her "out-of-control" diva behaviour.
The insider added: "She is getting a reputation as a bit of a pain in the a**e. She is such a diva. It's getting out of control."
The crew aren't the only people who are unhappy about the ban on meat.
Australian songstress Gabriella Cilmi - who is supporting Leona on the tour - also expressed concern over the vegetarian menu.
Speaking before the start of the tour, she said: "All I know so far is that the food's going to be vegan, and I'm not sure how I'm going to cope with that."
